Answer:
Artificial weight = 70.27 N = 15.80 lbs
Explanation:
The earth weight of the astronaut = 160 lbs = 711.72 N
The weight on earth = m × g(earth)
g(earth) = 9.8 m/s²
711.72 = m × 9.8
m = (711.72/9.8)
m = 72.62 kg
But at the space station, the space station rotates once every 70 s to create an artificial radial acceleration that creates a radial gravity pulling the objects on the space station towards the centre of that space station.
radial acceleration = α = (v²/r)
v = rw,
α = (rw)²/r
α = rw²
r = radius of rotation = 120 m
w = angular velocity = (2π/70) (it completes 1 rotation, 2π radians, in 70 s)
w = 0.0898 rad/s
α = 120 × (0.0898²)
α = 0.968 m/s²
Artificial weight = (mass of astronaut) × (Radial acceleration) = 72.62 × 0.968
Artificial weight = 70.27 N = 15.80 lbs
Hope this Helps!!!
Well when you eat you get energy and then you use it to ride up the hill sorry I don't know how it is classified
The energy is 3.06 electronvolts, E = 3.06eV
1eV = 1.6 * 10^-19 J
3.06 eV = 3.06* 1.6 * 10^-19 J = 4.896 * 10^-19 J
Answer:
Electromagnetic Radiation
Explanation:
Electromagnetic radiation is formed by the combination of electric and magnetic fields, which propagate through space in the form of energy-carrying waves.
Electromagnetic waves have vibrations perpendicular to the direction of wave propagation. For this reason, they are classified among the transverse waves.
Electromagnetic waves travel through space, and do not need a material medium to propagate.
Main types of electromagnetic radiation.
Gamma rays: More energetic radiation. It has the highest frequency (and therefore, the shortest wavelength). They constitute a form of radioactivity.
X-rays: Radiation of less energy than gamma rays. It is used in medical examinations and in the study of metals.
Ultraviolet (UV) rays: Radiation of less energy than X-rays. It comes mainly from the sun.
Visible radiation: Radiation of lower energy than ultraviolet rays. Collect the range of frequencies that can be perceived with the view, from red to violet.
Infrared rays (IR): Radiation of less energy than visible radiation. It is emitted by hot bodies.
Microwave: Radiation of less energy than infrared. It is used in appliances and medical therapy.
TV and radio waves: Less energetic radiation. They are used in telecommunications
The mass on the spring is bouncing.
We would call it a wave-like motion, except that it all stays in the same place. But, just like a wave, moving from the highest position to the lowest position
is one-half of a full wiggle.
(The other half consists of moving from the lowest position back up to the
highest position, where it started from.
So, half of the wave-like motion takes 0.6 seconds.
A full cycle of the wave motion ... the actual period of the bounce,
is double that much time . . .
1.2 seconds.
